The paper is devoted to the outlines of multilevel inverters and more in particular the form and function of topologies and recently used control schemes. In the recent years, the requirement of multilevel inverter is expeditiously increasing in the field of electrical energy utilization because the multilevel inverter is a key technology to integrate the renewable energy sources with the grid. Recently, various multilevel inverter topologies have been introduced which required a large number of power switches, gate drive circuit and voltage sources, as a result the complexity of the circuit, power losses and voltage stress on switch increases on the other hand the efficiency of the system reduces. The primary energy source can be for instance a battery, solar panel, fuel cell, generator etc. while the load can be anything from a motor to the connection with the power system. As will be shown with multilevel converters the number switch functions is increased, while increasing the power ratings with a switching frequency as close to the fundamental frequency. Multilevel converters provide and effective switching frequency increase allowing negligible filter requirements.
